Got the Continental winter contact si at CT. They were able to give me the promotion pricing 20% (manager override) they had a couple weeks ago. Paid with the rexall 10% off gift cards and did the mounting for $60 at a local tire shop.

Just make sure you check the date codes when buying from CT. I had a 2015 January tire in my set but I was able to exchange them all for 2017s.

Got the continental since Michelin excludes CT from the mail in rebate

Edit - looks like you can get Michelin rebate now from ct:
Please note that the MICHELIN $70 mail-in rebate cannot be combined with Costco (From October 13 to December 15, 2017)
and Canadian Tire (from October 20 to November 23, 2017) instant rebate.

New promo from Kal tire: Kal Tire is supporting local food banks with a special promotion! From Nov. 27 to Dec. 16, for each set of tires a customer purchases, Kal Tire will give $50 to the customer and match it with a $50 donation to the local Food Bank.

The promo can be combined with tire rebate or discount. I got the Nokian HK R2 SUV tires for my 2017 CR-V at $100 off: 50 from local food bank promo, and 50 from Nokian instant rebate. Used the membership to get another extra 10% off. Total paid $180.48 per tire for the HK R2 SUV. Bought the steel wheels from Costco to take advantage of 25 off masterpass offer. Total paid for the Nokian HK R2 SUV tires + steel wheels + installation + tax (AB) is $1118. Not bad I think.

I just bought last 4 General Tire Altimax Arctic Tire at my Canadian tires.
they were in clearance 99 dollars each from 179 (91dollars with rebate). I hope I scored a good deal, I don't know much about tires but I didn't have bigger budget
